Now this is interesting. A new theory–the plausibility of which I am not in a position to assess–suggests that there was no Big Bang. The universe is spatially finite, but temporally infinite. So there was no “beginning” to the universe:
“In cosmological terms, the scientists explain that the quantum corrections can be thought of as a cosmological constant term (without the need for dark energy) and a radiation term. These terms keep the Universe at a finite size, and therefore give it an infinite age. The terms also make predictions that agree closely with current observations of the cosmological constant and density of the Universe.”
Of course, if I understand relativity correctly (my main sources being Star Trek and Wikipedia), it is also perfectly possible that the Big Bang was not the beginning of the universe in any absolute sense, only of space and time as we know them. So what physics calls “the universe” may be simply one event within a macro-universe or multiverse. Like I said, I don’t pretend to understand any of it. I just think it’s cool.
But what does it mean for Christian faith?
